AB Hernandez, a transgender athlete, won gold medals in high jump and triple jump at a California high school sports event. This caused a lot of talk and got attention across the country. Hernandez could compete because of a new rule. This rule let another girl join if Hernandez was good enough. Some people protested because they do not want transgender athletes to play in women's sports. The new rule was made because of Hernandez's wins. It also follows California laws that let transgender students play on teams that match their gender. But some people think the rule makes things more confusing. Many adults in the States do not think transgender female athletes should play in girls' or women's sports.
